What is "Modesty of Speech"?

Mother reads from The Christian Mother and The Christian Father, and answers questions from: Bonnie in Lockport, who is concerned about Eucharistic Adoration with music and "entertainment"; Douglas in Ontario, who is wondering about detachment; Irene, who asks about Fr. Chad Ripperger's situation; Niall, who is upset about dogs being allowed at Mass; Diane, who asks if Nicodemus was born again and Catholic; and Chelsea, who requests an explanation of "modesty of speech".
